I think this is a challenging one sense ostensibly we learn that Tellarites had generation ships before achieving warp capabilities and that these generation ships went at least as far as the Delta Quadrant. I don’t know that we can so safely assume that Jankom Pog is representative of Tellarites in the Federation.
I mean let’s be clear for most of Ferengi history women were not allowed to own property of any kind - including clothing and some of their business endeavors include poaching endangered animals and literally being slave traders. I mean - I don’t think there’s any indication that Ferengi society was anything more than hyper-capitalist dystopia as a juxtaposition of the Federation socialist utopia. That Rom and Quark are goofy and lovable I think speaks more to how bad every other Ferengi is operating outside of a Federation station.
From the Federation’s perspective the Ferengi are harmless and in this way they may be ethical enough to not warrant confrontation, but at the same time - the Federation does seem to stop them when they’re doing something like slave trading so I think we can imagine that for some people in the sphere of Ferengi influence they’re not so ethical.
